Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X

Configuring Login Conditions
You can issue the dsr-detect command to configure the system so that a data set
ready (DSR) signal is required to log in to the console. If a session is in progress and
the DSR signal is lost, the user is logged out automatically.
host1(config)#line console 0
host1(config-line)#dsr-detect
DSR is carried on pin 6 of the SRP module’s RS-232 (DB-9) connector. The DSR input
must be connected to the DSR output of a modem or the DTR output of another data
terminal device, such as a terminal server, that supports this signal.
dsr-detect
■ Use to require that a DSR signal be detected on the line for a user to log in to
the console.
■ By default, DSR is not required and DSR detection is disabled.
■ Example
host1(config-line)#dsr-detect
■ Use the no version to remove the DSR requirement for login.
■ See dsr-detect.
Setting Time Limits for User Login
You can specify a time interval that the CLI waits for a user to provide a password
when logging in to the console or a vty line. To do so:
1. Access the line configuration mode using either the console or vty keyword.
2. Specify the time during which the user must enter the password. For example:
host1(config)#line console 0
host1(config-line)#login
host1(config-line)#timeout login response 15
timeout login response
■ Use to set the time interval that the console or vty lines wait for the user to log
in.
■ If the interval passes and the user has not responded, the system closes the
session or lines.
■ Specify an interval in the range 0–300 seconds. A value of 0 means that there
is no time limit during which the user must respond.
■ The default value is 30 seconds.
